Answer:

A) 50°, 65°, 65°

B) 45°, 50°, 85°

C) 20°, 60°, 100°

Step-by-step explanation:

To see if the angles can be used to construct triangles, you have to check if the degrees add up to 180 (Since the degrees in a triangle always have to add up to 180 degrees).

<u>A) 50° + 65° +  65° = 180° (Good!)</u>

<u>B) 45° +  50° +  85°  = 180° (Good!)</u>

<u>C) 20° +  60° +  100° = 180° (Good!)</u>

<em>D) 30° +  60° +  70° = 160° (Bad!)</em>

<em>E) 20° +  45° +  120° = 185° (Bad!)</em>

Which of the following is the solution to the differentiable equation dy/dx=4x/y, where Y(2)=-2
aliya0001 [1]

First we'll substitute \frac{dy}{dx} with y'

y'=\frac{4x}{y}

Then we can separate this.

yy'=4x

Then we'll solve this.

yy'=4x: \frac{y^2}{2}=2x^2+c_1

\frac{y^2}{2}=2x^2-6

y=2\sqrt{x^2-3},y=-2\sqrt{x^2-3}

Then we'll plug in to find the extraneous solutions (if any)

y=-2\sqrt{x^2-3}
